This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. The periaqueductal gray (PAG, also known as the central gray) is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. PAG is also the primary control center for descending pain modulation.

WebbAs mentioned, the periaqueductal gray region is in the midbrain. It expresses a lot of opiate receptors which can be triggered by exogenous opioid pain medications or endogenous opioids synthesized naturally by the body. The three families of endogenous opioid peptides that have been identified are enkephalins, endorphins, and dynorphins.

WebbAnxiolytic effects of CBD are induced with a bell-shaped dose–response curve when administered directly into the dorsolateral periaqueductal gray, an effect mediated by the 5HT 1A R . On the dorsal raphe nucleus, CBD acts as an indirect agonist of the somatodendritic 5-HT 1A autoreceptors, contributing to the anti-emetic effect [ 112 ]. WebbHere we discovered a subset of OT neurons whose projections preferentially terminate on OT receptor (OTR)-expressing neurons in the ventrolateral periaqueductal gray (vlPAG). Using a newly generated line of transgenic rats (OTR-IRES-Cre), we determined that most of the vlPAG OTR expressing cells targeted by OT projections are GABAergic.
